rIhis invention relates to tack-pulling machines and is illustrated as embodied in a machine for pulling temporary lasting tacks from boots and Shoes.

In the manufacture of a Welt shoe for eX- y ample7 before the welt is attached to the Shoe by the welt sewing machine, it is the general l practice to remove the lasting tacks which are insertedaround the Shank and forepart durj ing the lasting operation to hold the upper in lasted position, in order to avoid breakage of the tacks and to avoid breaking welt sewing machine needles yor thread. To facilitate this tack pulling operation, the lasting tacks around the shank and forepart of a welt shoe Y are only partially inserted. These tacks are,

however, driven in a row, and the several tacks are positioned relatively close to one another. Tack-pulling machines are frequently con-y structed with cooperating jaws arranged to grasp a tack and to pull it from the shoe as the latter is held against a work support. With such machines trouble has been experienced l `because in the rapid operation of the machine it has been impossible wholly to protect the upper from damage by the jaws and also to lprevent one of the jaws from occasionally engaging an approaching tack in the row and tending to drive the shoe awayA from the work support as it is held against the Vsupport by the operator. This is objectionable to the operator and reduces the efficiency of the machine by retarding the speed of operation. l

An object of the present invention is to provide an improved tack pulling machine which will be so organized as to obviate the difliculties above referred to and'which in this and other respects will be more accurate in operation, have greater output capacity, and in the use of which wear andy tear will be minimized.

To this end, in accordance with a feature of the invention7 the illustrated machine is providedwith pointed, tack pulling tools and is arranged to move the tools laterally of a row of tacks in a boot or shoe to insert the pointed end of one of the tools between' successivek tacks and then to move it awayv from the work in withdrawing a tack. As illustrated tools are moved inwardly in converging directions over a poi-.tion ofthe `bottom of a shoe to grip a ,y

relatedto said iirst movement and away from the shoe to pull the tack. As a result the machine is adapted to withdraw the temporary lasting tacks rapidly from the boot or shoe, even though these tacks are close together in the row, and the danger of damage to the upper by the movable tools and of accidental gripping of the upturned edgeof the upper by these tools is minimized. Besides this the `dis-.

position of the parts is such that the operator is given a fullview of the work. I

To assist the rapid presentation of the tacks in a row to the operation of the machine, in

accordance with another feature ofthe inven-y tion, the illustrated machine is provided with ya work support or rest in which there is a wide Anotch, having angularly `related edges with one of the edges arranged at an angle to the direction of movement of the tacks as theyy i are presented tothe machine and serving as a tack locating abutment. rlhe improved operation ofithe machine whereby its speed is increased and thedanger of interference between the Operating ,tools andA approaching tacks is minimized results to a large extent from the relation of the tack-pulling tools tor this notch and especially'tothe tack-locating abutment thereof. lnthe illustrated machine the pulling tools are provided with substan-,y tially parallel faces and are movable outwardly over the work support in converging direc- Y tions and then upwardly away from lthe work support to pull a tack. Onesof the tools moves over a solid portion of the work rest and has i its operative face substantially parallel to the length of its supporting lever `and arranged to be superpcsed above the tack locating abutment as it approaches a tack to be pulled. There is therefore no possibility of the fen-f' gageinent of approaching tacks in this tool until they are located against Athe abutment and ready to be pulled. The other cooperating tool-has its operative'face at an angle to the length of its supporting lever andv moves`r `in a direction making an acute angle withthe tack locating abut-ment across the other edge of the notch to a position behind the shank of the tack located against said abutment so that, incooperation'with the .other tool, it grips a tack positioned there. This provides a maXimum freedom from interference between approaching tacks and the tool and allows a rapid presentation of successive tacks to the locating abutment at any angle within a wide range. Both tools are then moved in a direction angularly related to the direction of gripping movement away from the work rest .to withdraw the tack.

Y Still another feature of the invention resides in the disposition of the moving parts of the machine so that suicient lubrication of the parts is assured. ln the illustrated construction the frame of the machine comprises an open topped receptacle which may contain oil, and the moving parts of the machine are mounted upon a cover for this receptable so that they are disposed within the receptacle and are bathed in oil during the operation of the machine. The tool carrying members pass forwardly through a curved, hollow horn-shaped projection or neck formed integrally with the cover above its level, thus avoiding the transfer of oil from the receptacle to a point where it might be thrown uponthe work.

In accordance with other features of the invention, the illustrated work or shoe supportor rest is pivotally mounted and is rigid- 'fly held against upward movement but resiliently Vheld against downward movement.

Damage to the machine is thus avoided in case a tack becomes wedged between the pullingv jaws and the work support. A depending, adjustably mounted finger is also provided adjacent to the end of the work support which may be brought into engagement with the upstanding edge of the upper to assist in guiding the work and, as illustrated, a defleeting member adapted to turn the edge of the upper out of the vpath of the pulling tools is adjustably mounted upon this linger.

v These and other features of the invention will now be described with reference to the accompanying drawings in which:

Fig. 1 is a side elevation of the machineV with parts broken away;

Fig. 2 is a detail View of the slidable support upon which the tool carrying levers are pivoted; Y

Fig. 3 is a fragmentary side elevation of the Vtools and work support viewed from the rear side as regards the direction of movement of the work; Y

Fig. 4 is a plan view of the machine with parts broken away and in section; and

Fig. 5 is a perspective view of the work rest i and the tack pulling tools, showing them in the position which they assume after they have started to pull a tack, this view being 1 taken in the opposite direction from that of Fig. 3.

v The shape of the work or shoe support or rest 9 and the tack pulling tools 10 and 11 may best be seen from an inspection of F igs.

4 and 5, from which it will be seen that the o-uter end of the work rest 9 comprises a substantially fiat plate 12 having a notched recess 14 the sides of which are substantially at right angles to form a wide throat for the admission of the successive tacks of a row. The rear edge of the plate 12, viewed as in Fig. 5, is curved to avoid interference with the work, and for a similar reason one corner is bent to form an upturned lip 1G to avoid any tendency toward disiigurement of the upper and further to allow tipping movement of the work so that the pulling tools may be brought into close relation to the upper 2U. This will allow the centerl ends of the tools to be brought beneath the head of a deeply driven tack, the head of which projects only slightly from the work. 1n lasting a welt shoe such as the shoe illustrated in Figs. 3 and 5, the upper 2O has been pulled tightly over the last 22 and the feather of the insole 28 with its upturned edge 24 in engagement with the outer lip 2G of the insole 28 and has been secured in lasted position by means of temporary lasting tacks 30. To assist the operator, when the work is presented to the machine, in guiding these tacks into the tack pulling position, as determined by the notch 14, a depending wedgeshaped linger 82 is adj ustably mounted and held by means of a screw 34 upon an arm 36. This finger is intended to be brought intothe angle formed by the upturned edge of the upper 2O as it rests against the feather 23 and the lip 26, and in order to preventany interference between said upturned edge 24 and the operating tools, a deflector 38 is adjustably mounted upon the lower end of the iinger 32. The forwardly extending edge 40 of the notch 14 serves as an abutment against which successive tacks are located as they are positioned in the notch.

It will be observed from Fig. 5 that the outer ends of the tack pulling tools 10 and 11 are curved downwardly and inwardly to form jaws 41 and 43, respectively, which have their operative edges substantially parallel, as shown in Fig. 4. From Fig. 4 it may be also seen that the outer ends of the jaws 41 and 43 are pointed and that their cooperating tack engaging edges are substantially parallel to the forwardly extending tack locating edge 40 of the notch 14 in the work support 9. The tack pulling tools 10 and 1l are adjustably mounted by means of suitable clamps 42 and 44 upon the outer end of converging levers 46 and 48, which are slidably mounted between suitable guides, to be hereinafter described, for movement in converging planes, and it will be observed that the operative tack engaging edge of the tack pulling tool 11 extends in a directicn parallel to the length of its supporting lever 48 and parallel to the abutment edge 40, while the corresponding edge of the tack pulling tool 10 is angularly related to its supporting lever 46.

Aisa

immaterial whether the tacks have been driven in a regular row along the edge of the shoe or whether they happen to be positioned at various distances from the lip of the vinsole and hence from the angle in which the guiding finger 32 is received because the machine will operate properly regardlessv of thev party of the abutment at which atack is presented. Another factor which aidsin the free presentation of tacks to the machine andthe assurance that they will be readily pulled from the work arises out of the disposition of the operative edges of the tack pulling toolsk with respect to one another and the abutment edge 40. It will be observed from Fig. 4 that the movement of the jaw 43 of the tack pulling tool 11 is wholly over a solid portion of the work rest and that lthe operative `edge of said jaw, being parallel to the length of the tool and at the same time to the abutment edge 40, moves outwardly over the work rest into a position where its operative edge is substantially coincident with the operative edge of the abutment. There can, therefore, be no interference between said j aw and the approaching tacks, Vand the angle ofpresentation of the row of tacks is independent of the operation of the jaw. The jaw 41 of the tool 10, on the other han-d, while it is bound to move from a posit-ion outside of the row of tacks into a position intersecting said row in order that its operative face may be brought from the rear into contact with the lshank of a tack located against the face ofthe abutment 40, has a movement, by reason of its guidance in a converging plane with riespect to the other parts of the machine such that the operative face of the jaw 41 occupiesan infinite number of successivepositions in planes parallel to one another and to the operative face of the jaw 43 of the tool 11 up to the gripping position, with the minimum of interference between the approaching tacks and the jaw 41. Sometimes it is required to 'pull the temporary lasting tacks without disturbing the anchor tacks holding the toe wire,

and it frequently happens that a group of Y tacks is found in close juxtaposition to one or the other of said anchor tacks. The withdrawal of the tacks of such a'group without disturbing the anchor tack is greatly facilitated by the pointed end of the jaw 41 and its manner of movement with respect to the abutment face 40. Thus if it is `necessaryto withdraw a tack which is spaced very close to another tack, the tack to be Withdrawn may be presented near theouter end Aof the abutment face 40 so thatonly the very point of the Vj aw 41'need rbe brought into position between two tacks, thus allowing an accurate 70 selection of a particular tack to be withdrawn and a positive withdrawal of said tack re.-

' gardless of the exact point onthe length of the operative faces lof the jaws lbetween `which the tack is gripped; Y

Adequate lubrication of themachine is provided by means comprisingran oil containing receptacle 50, suitably supported as by means of a column 52. The moving parts ofthe machine are mounted upon the under side of, a cover 54 bolted to -said receptacle and dip thereinto so that they are bathed inoil. The cover 54 has a transverse upstanding rib 56 (Fig. `1) provided with a bearing for a drive shaft 58 to which powermay be supplied as by avpuiley 60, and said shaft is connected .to the working parts of the machine by a gear 62.r kThis gear/'.62 meshes with a gear 64 ymounted upon an operating `shaft 66 carried in bearings formed in a depending rib 68-` made integral with or otherwise secured to the under side of the cover 54. The bearings for the shaft 66 are completed ,by cap plates 70 (Fig.` 2) bolted thereto. It will be observed that the cover 54 is provided with anv upwardly extending pocket 7 2 (Figs. l and 4) designed to overlie thegear 62.

In order to provide guides for rthe levers 46 and 48, a V-'shaped rib 7 4 is cast integrally with the cover on the under side thereof and the outer faces of said rib may be suitablymachined, as at 76 (Fig. 4), to provide converging bearing surfaces against which said levers 46 and 48 may slide. The outer bearing for said levers at ytheir rear ends may be provided by depending plates 80 having f' inturned lhorizontally disposed fia-nges by means of which said plates are adjustably mounted on the cover as by bolts 82 lpassing through slots in the cover. Bearings for the.V

outer tool-carrying ends of the converging levers are also provided by wedge-shaped blocks 84 adjustably secured to theV forward end of a hollow horn-shaped projection 86 (Fig. ,1) upon the cover by bolts 88 whichpass`A outer faces of each of the levers 46 and 48.1, 'Each yof the levers comprises a substantially horizontally disposed, bifurcated portion 92 (Fig. 1) at its rear end and aforwardly eX- tending, upwardly curved portion 94, which Apasses through the'horn-shaped casing 86.(

The horizontally disposed, bifurcated portions 92 are guided for movement infconverg-` faces 76 (F-ig; l), and the levers are pivotally ymounted near theircentrafl portionsiupon iio 'ing planes between the plates 80 and the surv`pins 96 (Figs. k1, 2 and 4) secured to a slide 98. This slide 98 (Figs. 2 and 4) is arranged for front to back movement in a plane bisecting the angle between the converging planes of the levers `46 and 48 and is supported upon horizontal rods 100 secured to the depending rib 68 on the cover 54. Reciprocation of this slide 98 is provided by a cam track 102 on the face of the'gear 64 and a cooperating roller 104 mounted upon a detachable bracket 106 secured to the slide 98. The levers 46 and 48 lare free to move laterally with respect to their pins 96, as will be seen to be necessary upon inspection of Fig. 4, in order that said levers may slide in converging planes angularly related to the plane of movement of the slide 98 upon which the pivot pins 96 are-carried.

By this and other mechanism to be later described, themovement in a vertical plane of a point upon either of the operating tools follows a path indicated by dot and dash lines in Fig. 3 and will be seen to comprise a sub- Y stantially horizontal forward movement 110 byv which the cooperating, thin edges of the jaws of the tack pulling tools 10 and 11 are brought beneath the head of a tack as said tools move laterally from a position where they, are outside of the line of tacks into a position intersecting the line of tacks. The tack pulling tools are next moved vertically, as at 112, to effect a tack pulling movementand are returned into position for a subsequent tack engaging and pulling movement over a curved path 114. It should be remembered that the forward horizontal movements 110 of the tools are in converging directions, bringing the parallel operating facesof said tools into gripping engagement with the sides of the shank of a tack, which relation is maintained during the vertical movement 112. After this, in their return movement 114,

`the tack pulling tools move in diverging directions and release the tack.

ln order to impart this compound movement to the tack pulling tools, provision is made for tilting the levers 46 and 48 about the pivotpins 96 and to this-endcoacting bearing blocks 120 and 122 (Fig. 1) are received between the bifurcated ends 92 of said levers and are arranged to surround ball-shaped ortions 124 see Fig. 4 which are eccent3 7 trically formed upon the operating shaft 66, as indicated in dotted lines in Fig. 1, so that the combined action of said eccentric, ballshaped portions 124, in tilting the levers 46 and 48, and of the cam operated slide 98 in moving the levers toward and away from the tacks is effective to produce t-he path of movementdelineated in Fig. 3. It will'be observed that the bearing blocks 120 and 122 may slide laterally with respect to the bifurcated ends 92, and provision is made for taking up wear between said blocks and the ends 92 of the levers by means of adjustable gib plates 126,

the position of which may be adjusted by means of screws 128 (Fig. 4).

Blocks 130 are bolted to the under side of the horn-shaped projection 86 of the cover 54, which provide a support for a transverse pin 132 upon which the work rest 9 is pivotally mounted, its upward movement being limited by bearing against a suitable portion of said blocks 130 as it is resiliently held in operative position by means of a spring 134 surrounding a stud 136. This prevents the possibility of breakage in case a tack should become jammed between the tools and the forward end of said work rest while at the same time providing a rigid support holding the shoe against upward movement as the tacks are withdrawn from the work.

The bracket 36 supporting the grinding finger 32 is adj ustably mounted upon the upper/side of this same horn-shaped portion 86' and is held in adjusted position by means of screws 140 which may also be utilized to clamp in position a guard 142 extending outwardly and downwardly and provided with slots within which the tack pulling tools operate. If desired, the screws 88, by means of which the wedge shaped bearing blocks 84 are held in adjusted position may also be utilized to hold a cover 144, a fragment of which is shown in Fig. 1, which is arranged to extend outwardly over the upper side of the operating parts at the front of the machine.

There is thus provided a construction by means of which a single operative shaft passing across the diverging ends of the tool carrying levers 46 and 48 is elfective to tilt said levers and to move them forwardly and backwardly in converging planes to bring the tools beneath the head of the tack, to lift the tools to pull the tack, and then to return them to starting position with a simultaneous release of the tack. 1t should be observed that in this movement the edge of the tack pulling jaw 43 moves in a right line substantially parallel to the abutment edge 40 of the notch 14 in the work support and that the tool itself overlies a solid portion of said work support during substantially its whole path of movement. As a result, interference between this jaw and the tacks being presented by the operator is practically eliminated. A uniform and continuous forward movement of the work as the operator presents the shoe to the machine is provided and interference between the other tack pulling jaw 41 and the tacks is minimized because of the pointed formation of the forward end of said jaw, whereby, as it is moved substantially horizontally from a point without the line of tacks to a point intersecting said line, it is allowed to pass between successive tacks and substantially eliminates danger of driving tacks inwardly. In addition, the horizontally movement of the jaws, as they are brought into tack pulling position above the work rest 9,

ciprocating avoids danger of damage to the upper of the shoe, the possible grasping of the'upper by the jaws, and allowsfull vision of the work as the operator presents the tacks into the notch 14 of said work rest 9.
